No, the 270 is the clock master on the I2S bus. The codec is sourcing the clock input using the PLL. I apologize for being unclear.
I think it's me that's not being clear, sorry - I'm trying to find out is if the LRCLK and BCLK signals on the I2S bus itself are being driven by the codec or by the I2S controller. If the codec driver is the clock master then your earlier speculation that your problems with the I2S controller may be due to some interaction with the codec driver are more likely to be true.
